My scanner is much slower while scanning under linux than it is under
windows; even lineart scans at 100 dpi aren't scanned in one run but
the scanner repositions every few seconds.
Adding dma to to the parport driver as well as forcing to ECP (BIOS)
didn't help anything.
Any ideas, how to improve the speed? I didn't find anything in the
archives, but maybe I did the wrong search ... any hints appreciated!
